Fans of Andy Warhol have been visiting the late artist's grave site and leaving cans of Campbell's Soup, the very same can that he is so infamous for painting. Others have left items such as bottles of Coca-Cola or Chanel perfume.

The shrine, located just outside of Pittsburgh, has been documented by Madelyn Roehrig, an artist who has been working on a project for four years called Figments: Conversations with Andy.

"Sometimes there are so many soup cans up there, there's like two rows of them," Roehrig said. "Mainly tomato, and chicken noodle, and all the varieties of chicken noodle. Now you're getting low fat, low salt. And then some of the competition. Cup-O'-Noodles show up every once in a while, and it kind of stands out, you know. I don't know why somebody would want to do that, but they do."

Roehrig says she visits Warhol's grave daily to take pictures of the items and notes fans leave behind. The video below is a compilation of photographs of Warhol's grave from March 2009 to March 2011.
